Patent GB-1051162-A (GB)
IPC: B42F9/00
Filed: 1963-05-31
Abstract: 1,051,162. Heat exchanger tube supports. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 28, 1963 [May 31, 1963], No. 22024/63. Heading F4S. [Also in Division G6] A grid structure for positioning a group of heat exchange tubes within a pressure tube carries on its periphery an entirely separate ring for bearing against the pressure tube wall, said ring being of a different material to the remainder of the grid structure. The bearing ring is split for easy replacement, and is of such a material (e.g. zincalloy) as to wear in preference to the pressure tube when relative sliding takes place. Alternatively it may be made of substantially the same material as the pressure tube in order to obviate fretting corrosion. It is preferable to provide splines on the internal surface of the pressure tube to engage the bearing ring, and the latter is preferably oversize to maintain compressive engagement with the splines. As seen in Fig. 1, the bearing ring 14 is retained between two flanges 13. A continuous spring 20 is sandwiched between the bearing ring 14 and an outer grid ring integral with one of the flanges 13. The grid structure 16, 17, 18 is of spot-weld construction, and is spot welded to the outer grid ring. Apart from the bearing ring 14, the entire grid structure is of stainless steel. In a modification (Figs. 3, 4, 5, not shown), the flanges 13, the spring 20 and the outer grid ring are replaced by a single insulating clip having tags sheared from its central zone; the tags are spot welded to the grid structure and the bearing ring is located in the apertures of the clips formed by the displacement of the tags. In a second modification (Fig. 7, not shown), the flanges 13 of Fig. 1 are replaced by tubes. The heat exchange tubes assembly shown in Fig. 6 comprises a series of pressure tubes connected alternately by branch tubes 30 at their tags and U tubes 31 at their bottoms. Light water coolant is circulated both internally and externally of the pressure tubes.

Abstract: 869,852. Liquid fuel burners. LUCAS (INDUSTRIES) Ltd., JOSEPH. July 3, 1957 [July 23, 1956], No. 22687/56. Class 75(1). A liquid fuel nozzle includes a swirl chamber having a discharge orifice i .and an axial orifice k at its base leading to a cavity m connected by passages q, p, r, to air ducts g terminating in a discharge orifice w coaxial with the discharge orifice i of the swirl chamber. At low rates of fuel supply to the nozzle no air core exists at the axis of the swirl chamber and consequently fuel passes through the rear orifice k and the passages q, p, r to the air ducts g where it is nebulised by the airstreams and the mixture is discharged through the discharge orifice w. At high rates of fuel supply an air core forms in the swirl chamber and prevents the fuel from passing through the rear orifice k; the fuel therefore is nebulised by the swirl chamber and is discharged through the front orifice i. The nozzle comprises a hollow nipple having on its conical forward end helical grooves providing the air ducts g. An insert e co-operates with the nipple d to provide the swirl chamber, the base orifice k, the cavity m, the passages p, q, and further passages n, o which deliver fuel to the swirl chamber. A further insert f has fuel passages s conveying the fuel from a passage b in the nozzle body to the passages n. Air is conveyed from a passage c in the nozzle body to an annular passage t between the nipple d and an inner sleeve v. The parts are secured in position by an outer sleeve x screwed to the nozzle body and spaced from the inner sleeve v to form a further air passage which directs air across the front of the nozzle.

Abstract: 1,041,166. Contact printers. NATIONAL CASH REGISTER CO. May 28, 1965 [June 10, 1964], No. 22729/65. Heading G2A. In a photographic contact printer, a strip of film 21 and a master 16 are squeezed together be tween a transparent cylindrical roller 27 and a roller 26 having a resilient cover 28 which has a larger diameter at its centre than at its ends, the strips being exposed therebetween. The roller 26 is mounted on a continuously driven axle 31 rotating in bearings 32, 33 which are mounted so as to enable the pressure of roller 26 on the roller 27 to be adjustable The roller 27 is freely mounted on a fixed shaft 39. Light from a pinhole source 48 is stopped by a mask 51 having a narrow rectangular opening and is then directed by a stationary mirror 53 to form a narrow rectangular exposing (printing) station for the film 21. The shape of the cover 28 ensures that the centre of the film is pressed into contact with the master first, thus flattening irregularities in the emulsion surface and allowing air to escape from between the strips. The light source may be arranged to direct light more than once through the cylinder wall 36. The master 16 may be wrapped around the wall 36 to make more than one copy without having to rethread the master.

Title: Hydrogenation of oxyheterocyclic compounds
IPC: C07D309/04
Filed: 1959-07-03
Abstract: Furan, methyl furan and dihydropyran are hydrogenated to produce tetrahydrofuran, methyltetrahydrofuran and tetrahydropyran respectively, by contacting the compound, in the vapour phase in the presence of a reduced nickel catalyst and an amine, with a hydrogen-containing gas at a hydrogenating temperature of below 120 DEG C.  The amine acts as a selective poison for the catalyst. Aliphatic, aromatic or heterocyclic amines or mixtures of amines may be used, preferably in an amount between 0,01% and 0,1% by weight based on the amount of starting material.  When furan is the starting material the preferred temperature range for the reaction is 70-80 DEG C., with methylfuran it is 60-65 DEG C. and with dihydropyran the reaction is preferably carried out at about 70 DEG C. The nickel catalyst may be used as such or may be supported with one of the usual supports and certain basic substances, such as sodium silicate, calcium oxide or magnesium oxide, may be added to it.  Preferably an excess of hydrogen, which may be diluted with an inert gas is used.

Title: Improvements in or relating to the production of moulded articles
IPC: C08L61/10
Filed: 1935-08-14
Abstract: A moulded article is made by first building up a laminated structure of fibrous sheets impregnated with a resin that can be hardened by heat and roughly shaping the structure to the required form without alteration of the resin.  The roughly shaped article is then coated with a heat hardenable resin in liquid form and subjected to heat and pressure to harden the resin and to shape the article to its final form.  The impregnated fibrous sheets may be made by dispersing an emulsion or suspension of a phenolic resin in an aqueous pulp of wood or rag and forming the pulp into cr<\>zeped sheets.  The wet sheets are superposed to form the laminated structure which is then pressed roughly into shape and coated with resin either before or after drying.  This coating may consist of a varnish containing one hundred parts of phenolic resin in one hundred parts of ethyl alcohol and thirty parts of butanol, and may be applied by dipping or spraying. The coated shape is pressed in a mould to its final shape at a temperature sufficient to harden the resin.  Pigments or dyes may be incorporated in the final resin coating.

[Classes 40 (iii) and 40 (v)] To produce trains of synchronizing impulses, an alternating potential is applied in phase opposition to a pair of valves 1, 2, which are so controlled that only one operates during one train of impulses, but each in turn operates during successive trains, and the outputs are combined. The valves are rendered normally inoperative by a negative grid bias 4 and alternatively operative by a square-wave potential of such value as to overcome partially the negative bias on alternate valves during successive half cycles. The wave length of the square wave is exactly an even integral multiple of that of the sinusoidal alternating potential. The input circuits of the valves are in push-pull, and the valves have a common anode resistance 5. Specification 437,339 is referred to.
